To all whom 'it maid/concern:

Be it known that I, WILLIAM l?. BETTEN- nonr, a citizen of the United States, residing at Davenport, in the county of Scott and 5 State of Iowa, have invented new and useiful Improvements in Underfranies for Cars, of Which the following is a iull, clear, and eX- act description.

i My invention relates to the underirames of railway cars, especially underfrarnes that are constructed Wholly or partly of metal, In the make-up of underirarnes or this type, especially where the center-sill is made of I-beanis and the draft-sills are inade of cast-- metal, the Weakest place in these elements is at the point where one or the other is intersected by the body-bolster. In order to accommodate said body-bolster the vertical web, and sometimes the lower flange of the center-sill and the draft-sills are cut-away f to arch over the same. This displacement of the metal of the center-sill or the cast draftsills of necessity weakens that particular ortion oi:l the underfraine, and it is thereore the objectof my invention to construct both the center-sill and the draft-sills in a novel manner so that the body-bolster may be passed through the same without appreciably aii'ecting the strength of either. This I accomplish by lapping the adjacent ends of the center-sill and the draft-sills past each each other, riveting or otherwise securing beam. This center-sill entends longitudinally toward the opposite ends oi the car beyond the transverse plane of the bodybolsters B, and terminates between said loolsters and the end-sills la of the saine. fit the te points Where the plane of the body-holsters intersect the center-sill, the metal of the vertical web oiy the latter is,-preterably displacedto form openings that conform in shape to the transverse contours of the loody- 65 holsters..

Secured-to and extending beyond the ends of the centensill are suitable oppositely shaped draft-sills C, C, for the reception and retention of the draft-rigging (not it?, shown). These draft-sills are preferably of cast-metal and form bifurcated extensions of said center-sill, the ends of which farthest therefrom are secured to the end-sills b. The inner ends of these draft-sills lap past 755 the adjacent ends of the center-sills and extend past the transverse vertical plane oi' the holsters. At the point of intersection oi the center-sill by the body-bolster the Webs of these draft-sills are provided 'with open- 2i@ ings similar to that made in the center-sill, and these openings are, preferably, surrounded by integral lateral flanges 0, c, between which the bolster B passes and is secured. These iianges, c, project laterally 235i from the central vertical web of the draftsill casting a distance preferably correthe same together, and passing the bodysponding to the Width oi the upper and bolster through a suitable opening made in l lower flanges of the center-sill, and the louter said sills, all in the inanner hereinafter fully l portion oi' 'llanges c may be reinforced, if 9@ described and as particularly pointed out in desired, to orin a shelf c as it were, that the claims. l adds rigidity to 'that portion of the under- Referring to the accompanying drawings, i frame. In this construction the bolster is which form a part hereof, it Will be seen necessarily elevated lo a plane too high to 40 that, Figure l is a longitudinal central secperinit the center-bearing of the car to he 95 tion taken through the floor, undertramc, secured directly thereto. I therefore prefer y and truck of a railway car, showing the nianto malte this bearing of a plate D, that is ner of applying my improvements thereto. shaped so as to be secured to the underside Fig. 2 is a transverse vertical section of the of the lower flange et' the center-sill, and is 45 saine taken in front of the holsters and lookprovided with a downwardly elongated lil-l0 ing toward thevopposite end of the car. Fig.v bearing-boss ci, the center o'li which is in 31s a fragniental plan view of one end porvertical alineinent with the point of intersection of my improved center-sill and one sidetion of the bolster and center-sill, A tuill of the undert'raine. Fig. Ll; is a side elcvoular-shaped core (Z projects upwardly from 'the center of this boss?! and provides 195 a suitable socket for the upper end or' a king-bolt E that is retained therein by l means oi. a transverse pin c passedwthrough l said core and boss (as shown in detail in l 2 of the drawing). The bearing for traine from which Ythe truc-lt and other parts have been removed.

In the drawings, A, represents a suitable center-sill, vthat, is constructed, referably, of a suitableY single vcommercial orrn of I- the lower end of the king-bolt E, preferably, comprises a suitable hollow sleeve F arranged 1n vertical alinement with the core d and which is provided with laterally projecting brackets or webs f that are riveted or otherwise secured to the vertical webs of the metallic construction forming the truck-bolster G of the car. Mounted on the top of the truck-bolster, midway its ends, is the female bearing-plate H, having a central opening down through which the kingbolt passes, and having its circular ange or concentric rib 7L of such shape as to form a seat for the lower portion of the male bearing-boss.

ln view of the body-bolster and truck-bolster resulting from my improved construction it is necessary to elongate the side-bearings of either the truck-bolster or the body-bolster. These side-bearings I and J are made in the usual manner and are riveted to the body-bolster and truck-bolster at points just inside the vertical plane of the side-frames of the car-truck, and I preferto make the side-bearin r of the truck-bolster the elongated member, substantially as shown.

f The construction of the truck and sideframes herein shown are very similar to those set forth and described in United States Letters Patent No. 849,194, granted to me April 2nd, 1907, for improvements in car-trucks,j and therefore needs no detailed description herein,
